Question

我有一个警告对话框，为用户提供两个选项：yes和no。选择no后，AlertDialog会关闭，但选择yes后会让用户在线向他们发送指示，但当我返回应用程序时，AlertDialog仍然是可见，当点击是时，我似乎无法自动消失。以下是我的代码：

AlertDialog.Builder alert_confirm = new AlertDialog.Builder(TrackingServiceActivity.this);
alert_confirm.setMessage("Are you sure you want directions to " + data.name +"! Tracking will be suspended if it has started!");
alert_confirm.setCancelable(false).
alert_confirm.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                getDirections(latitude, longitude, data.lat, data.lon);
                stopTracker();
                return;
            }
        });

alert_confirm.setNegativeButton("No",new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                return;
            }
        });

AlertDialog alert = alert_confirm.create();
alert.show();

Answer 1

在“正向”按钮单击侦听器

中使用此功能

getDirections(latitude, longitude, data.lat, data.lon);
stopTracker();
dialog.dismiss();

Answer 2

在Yes侦听器中使用dialog.dismiss();。

 public void onClick(DialogInterface dialog, int which) {
                                        getDirections(latitude, longitude, data.lat, data.lon);
                                        stopTracker();
                                        dialog.dismiss();
                                        return;
                                    }

Answer 3

你错过了dismiss();电话。就这样做：

AlertDialog.Builder alert_confirm = new AlertDialog.Builder(TrackingServiceActivity.this);
alert_confirm.setMessage("Are you sure you want directions to " + data.name +"! Tracking will be suspended if it has started!");
alert_confirm.setCancelable(false).
alert_confirm.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                getDirections(latitude, longitude, data.lat, data.lon);
                stopTracker();
                dismiss();
                return;
            }
        });

alert_confirm.setNegativeButton("No",new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                return;
            }
        });

AlertDialog alert = alert_confirm.create();
alert.show();

Answer 4

删除此行

alert_confirm.setCancelable(false);

[setCancelable:][1]设置对话框是否可取消。默认为真。

AlertDialog不会关闭
